Chemistry-Course A. 

Physics of Chemistry. 

Fundamental conceptions, page i.* Densities, 9. Crystallog- 
raphy, 12, as reading matter, unless models of crystalline forms are 
available. Temperature and heat, 24. Laws of gases, $^. Kinetic 
theory of gases, 34. Maxwell's definition of a molecule is : "A 
molecule is that minute portion of a substance which moves about as 
a whole, so that its parts, if it has any, do not part company 
during the motion of agitation of the gas." The determination of 
gas densities, 41, gives the relative masses, commonly called molec- 
ular weights, of gaseous molecules.

may be made with a moderate supply of chemicals and apparatus obtained from 
druggists.

Course B. 



The work in this course is a continuation of that of Course A, 
with special reference to the theories of chemistry. The text-book 
is Remsen's Theoretical Chemistry. 

The student is advised to read, in connection with the text-book 
work, the following : 

The Historical Introduction and the General Principles of the 
Science in Roscoe and Schorlemmer's Treatise on Chemistry. 

The Historical Introduction under the head of Chemistry, and 
the article on the Atom, both in the Encyclopaedia Britannica. 

Roscoe and Schorlemmer, the Encyclopaedia, or Watt's Diction- 
ary of Chemistry, may be consulted for more complete descriptions 
of compounds than found in text-books.
